The winner is #4 Teacher of One.
This is a very interesting math curriculum. It is based on math history. Now, if you've read A Thomas Jefferson Education, you'll know that there is a contingent of people that believe that math should only be taught in context. In fact, some people even believe that math should be taught by reading through The Principia : Mathematical Principles of Natural Philosophy as a method of teaching math. I think there is some merit to the true mathematician reading Principia, but do not see the merit for most school children. I think it would be overwhelming.
On the other hand, anything that is worth learning is worth learning in context. Math is no different. The difficulty has always lain in finding context for math while teaching it. That is where Living Math comes in. This is a fun curriculum that includes reading a lot of books (something that I'm obviously interested in), learning about math in historical context, and generally learning more about math than most math teachers know.
Today, I am giving away one unit of this wonderful program. You pick which unit and level you want, and I'll order it for you. Just leave a comment with your email address. This giveaway will end March 3rd- World Math Day! Be sure to visit the other math giveaways while you're here.
For those trying to find the units (they're under lesson plans), take a look at these two links: Cycle 1 and Cycle 2.
